    Average number of even number outcomes = 5

    Step-by-step explanation:

    Probability = number of possible outcome / sample space

    A fair die has sides labeled 1,2,3,4,5,6.

    Therefore sample space = 6

    Odd numbers = 1,3,5

    Possible outcome of odd numbers = 3

    Even numbers = 2,4,6

    Possible outcome of even numbers = 3

    Probability of even numbers = possible outcome of even numbers / sample space

    Probability of even numbers = 3/6 = 1/2.

    If the die is rolled 10times

    Total number of outcome = 10

    Average number of even number outcomes = probability of even numbers * total number of outcome

    = 1/2 x 10

    = 5

    Average number of even number outcomes = 5

    3/6=1/2 so one half

    Step-by-step explanation:

    3/6 * 10 = 30/60=3/6=1/2
